Vancouver, British Columbia, Mr. George Salamis, President and CEO of Edgewater Exploration Ltd. ("Edgewater" or the "Company") is pleased to announce an increase in the Resource at the Company's Corcoesto Gold Project, Galicia, Spain. The inclusion of recent drilling completed by Edgewater in an updated geological model has increased the contained gold ounces in the Corcoesto resource by 3% to 325,000 ounces for measured and indicated gold resources and by 30% to 1,149,000 ounces of inferred gold resources.

President and CEO, George Salamis, adds; "In 2010 Edgewater acquired the Corcoesto Gold Project which, at that time, contained 324,000 oz of gold measured and indicated and 38,400 ounces in the inferred category. Since then we have successfully increased the gold resource by 400%. With the 2011 increased resource we now feel that Corcoesto has the potential to demonstrate economic viability and therefore this resource will form the basis of a scoping study to be completed in 2011. Based on this increased resource I am confident the scoping study will demonstrate positive economics and therefore will result in an increased value for our shareholders. In addition, the local support demonstrated for the project at all levels of government supports our view that Corcoesto will one day become a viable gold producer."

Significant features of the Increased (2011) Resources include;

initial deeper resource at Cova Creo of 45,000 oz grading 4.09 g/t Au which is currently the highest grade for any individual resource area

increase in grade for near surface resource at Cova Crea from 1.50 g/t Au to 1.67 g/t Au and the zones remains open

the near surface portion of the Peton de Lobo Zone was extended approximately 150 metres to the east by recent drilling and remains open (additional drilling is planned). The deeper portion of the Peton de Lobo resource decreased in grade due to lower than expected grades in drill hole 10W01.

Details of the Updated Resource (2011) compared to the previous (2010) resource are as follows;

CIM definition standards were followed for the resource estimate

The 2010 and 2011 resource models used an inverse-distance-power (IDP) grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids.

A total of 19,075.7 m of surface trenching in 225 trenches, 443.1 m of adit sampling in 4 adits and 42,111.18 metres of diamond and RC drilling in 342 drill holes were used in the resource with sample spacing's that were less than 30 m for Measured resources, less than 40 metres for Indicated resources and less than 195 m for Inferred resources except for Inferred resources below 200 m from surface and for the northern two vein systems that used drill spacing's of 196 m

A base cutoff grade of 0.65 g/t Au was used for reporting resources above a depth of 200 m from surface and a cutoff grade of 2.0 g/t Au was used for reporting resources below 200 m from surface

Dilution is included for a minimum mining width of 2.0 m on a 4.0 m high mining bench

Mineral Resources that are not mineral reserves do not have economic viability

The Updated (2011) Mineral Resource estimate was based on 42,111.18 m of diamond and RC drilling in 342 holes as well as surface trenching and adit sampling data. The Mineral Resource includes drilling results that were not included in prior resource estimates including deep drilling.

Work has also begun on the Scoping Study ("Preliminary Assessment" or "PA") on the Corcoesto Gold Project which will model the Project using the expanded resource and including the evaluation of both open pit and underground alternative and synergies. The PA is scheduled to be completed in 2011. One diamond drill rig is currently active on the Corcoesto Gold Project conducting a program of step-out and infill drilling to further define the total resource potential on the project.
